Application filed May 20, 1904. Serial No. 208,876.

curing a welt or a randto stock, and has for its object to provide means for slitting a welt or rand as it is being secured to the stock. The slits are formed to prevent it from puckering where it is curved to conform to the outline of the stock towhich it is being secured.

Another object of my invention is to provide means for rendering the slitting means inoperative without affecting the o cration of the securim means so that the slitting of the Welt may be confined to such portions as it is desirable to slit for proper attachment,

. and still another object is to provide a clamping device for'holding the welt or rand immovable while it is being operated on.

- .In the construction herein shown, which represents the preferred form. of my invention, the means for securing the welt or rand to the stock comprises a fastening-inserting machine, and the means for slitting the welt or rand comprises a recip rocatin'g cutter with which said machine is provided. -'Also, in the preferred form of my invention, the means for rendering the slitting means inoperative is under the control of the workman.

Figure l is a partial front elevation of a fastening inserting machine provided with means for slitting a welt or rand as it is being secured to stock; F ig. 2 is a partial side elevation thereof; Fig. 3 is a detail showing the cutter carrying lever and its actuating cam;

Fig; 4 is a like view showing the same parts but with the cutter lever occupying its lnoperative position; Fig. 5 is a perspective dctail showing part of a shoe sole and a Welt applied thereto, and the means for guidin the welt while being laid on a curved part the sole, the cutter being omitted. The fastening-inserting machine which I have herein illustrated is of well-known construction and is shown in United States Patcnt No; 490,625, dated January 24, 1893, and

in Patent No. 611,405, dated September 27,

1898,. said machine being designed to drive fastenings cut successively from a nail strip into a welt or rand to secure the same, re-

spectively, to a sole or a heel. The arm C" I having the hub C for sustaining a rotary nail "strip carrier, not shown, the lever G for slid-' ing the hub C forwardly and backwardly, the driver bar Bhaving a nail driver I), the nose f lever f 3 carrying the movable cutter of the nail cutting mechanism, the o posed cutter f 4 made adjustable by a screw and the main shaft B having at its front end a hub'having a projection 2 shaped to raise the driver bar and driver against its usual actuating spring, are substantially as shown and described in said Letters Patent, said parts being actuated as therein providedfor.

he machine is also rovided with a circular work supporting tabfd a 'yieIdingIy sustained y a spring a surrounding a rod a which is connected at its up er end to the table and at its lower end to a oot treadle, not shown, I

the de ression of the treadle operating to lower t e table. The table has teeth a that are engaged by a long inion b having at its upper end bevel teeth j that are in engagement with bevel teeth I; rigidly connected to a feedingwheel b that acts on the upper side-of thewelt or rand in contactwith the sole or heel sustained on the table a". The feeding wheel I) in tained in a bearing a having its foot connected by a screw a with a block a secured to the column A artially shown in Fig. 2.

I will now descrih I with which the machine previously described has been provided.

The hub at the front end of the shaft 13 is provided with a cam 2 that. acts upon mounted on a sleeve 5 extended from the hub 6 of the cutter carrying lover 7, mounted loosely on a stud 8 sustained-in a part of the framework A of the head of the machine, the stud .being shown in section in Figs. 3 and 4, 'the head of the'stud being represented in Fig. 1. The lever 7 is with acutter 10 held in means of 'a clamp or set' screw 12. The end of the lever 4 has a stud 13 over whichis hooked one end of a spring 14 that at its upper end isconnected with a stud 15 sustained by the head. The lever 7 has a stud 16 with which is engaged one end of a spring I 17, that at its upper end engages a stud18 e the slitting mechanism ractice will be carried by a shaft suslfO rovided at its end justed position by at its upper end a shoulder 20, and a springv 21 bearmg against one side of said dog acts secured to the head, as shown in Fig.2. The spring 14 actsv normally to keep the rollerstud 3 against the cam 2, and the spring 17 acts to return the'lever 7 into its starting osition after each operation thereof. The ever 7 has pivoted upon it a dog 19 having normally to keep said dog in contact with a thereof, viewing disengaging devlce shown as a cam projection 22, see Fig. 2, extended from the right hand side of a web n extended from a rock-shaft 23 mounted in bearings 23 carried by astationa part of the head and having at one end a andle n. The web alsohas a projection 22 extendin -from the left hand side ig. 2, which constitutes a stop to limit the upward movement of lever '7-u'nder the influence of spring 17 and also shown in Fig. 3, the spring 21 turns the dog,

19 and causes the shoulder 20 thereof to contact with an car 24 extending from the lever 4, and at such'times the depression of said lever acting through said dog depresses the lever 7 on which the dog is mounted, and the cutter is operated, but whenever the shaft is turned into the position shown in Fig. 4, the

50, rece tion 0 thecutter as the latter acts to sht t e welt or rand as shown in Fig. 5. The

projection 22, called the disengaging device acts against the dog. 19' and turnsthe same to release the lever 4, and thereafter the shaft B and its cam 2 will rotate and move the lever 4 without however operating the lever 7 and its cutter.

As shown in 2, the bearing a has coni nected to it by Its h andih a stand a shaped at its u per end to constitute a guideway a with side walls a, a, the latter side wall serving as a guide for the outer edge of the welt or rand was the latter is being fed through the, guideway and being secured either to a sole S, or a heel sustained on the table a, the bottom late or-part of the guideway being rovide with a space e for the wall or has a hole a that permits the entrance therethrough of' the shouldered. end of the edge gage '0, shown as a lever c pivoted at c on an earprojecting from wall a, saidgage acting'upon one edge of the weltrto hold it 1n engagement with the opposite wall a of the guideway. The edge gage lever c has a tubular portion 0 threaded for the reception of a screw 0 and a spring 0 is interposed be tween the end of said screw and the side wall a, of the guideway, to cause'the gage to bear upon the edge of'the welt with a yielding pressure. Whenever itis desired to remove will press upon the end ctof the lever to remove the notchedend of th'e; gage from the edge of the'welt. The side walls a and a of the'guideway receive a pin 2 having secured to it by a of which bears upon the upper side of the welt in its passage through the guideway a The pind extends beyond the ear (1 on the side wall a and is surrounded by a spring 1 one end of which is connected with the ear end of said pin, said spring acting to keep the ment with the welt, and thereby form a clamp'which will permit the welt to be fed through in the direction of the arrow in Fig. 5, but will prevent movement in the opposite direction.

It has been found very desirable to hold the welt or rand immovably in position durin the time that the fastenings 33 are being driven therein to unite the same to the sole slit the welt o'r rand, and to accomplish this an auxiliary pressing device is provided, said device comprisin a lever e mounted on a pivot e sustaine by ears e on the upright a the forward end of the lever extending free end of the resser 31.

The rear en of the lever e has a hole through which is extended a rod e connected to the foot treadle, before referred to, which operates the rod a for depressing thetablc aflso that whenever the treadle is de ressed to lower the work table, the rod 12 wi l operate to turn the levere and remove it from contact with the welt or rand presser 31.

ation bf the machine is actuated intermittinglyand automatically by or through the lower end of the arm C acting upon a yielding pin 34 mounted in a tubular art 35 of said ever a, theshank of saidpineing surrounded by a s iral "spring 36. Each time the lower end 0 thearm C is moved to the rial, the pin 34 is struck 'and turns the lever .12 so that its end which projects over the guideway will act upon the free end ofthe presser 31 to force it down upon the welt or rand to positively clamp it and restrain any movement thereof during the action of the driver in driving fastenings, and of the cutter in slitting the welt. .The s ring 36 also ermits the pin 34 to yield whi e the lever c 1s turned by the rod e in order to release the pressure of the lever e on the presser 31 as when a welt is being inserted.

condition, may thus'be left unslitted.

T he sole. or heel to which the welt or rand is being attached is fed over the table as provided for in said Patent #611,405, and 'is slitted while the table'is at rest between successive feeding movements and while a fas tening is being driven. The fastening made from'thc fastening strip, as provided for, is driven into the welt or rand while the latter is held firmly'in position by the presser 31, and as the arm C is moved to the rightof Fig. 2, away from the stud 34, the spring 36 is slightly relaxed. This relaxation of the spring also relieves the pressure of the end of the auxiliary presser on the presser 31 so that the only tension to which the welt or rand is subjected while the sole or' heel is being fed pre aratory to driving another fastening; is t 1e tension derived from the spring d j I believe that I am the first to slit the edge of a welt or rand while it is being applied to a sole or heel and being secured in position, and I desire to claim this broadly,-the term to cover a rand also. I believe also that I am the first to provide slitting means which can be operated to slit the welt only at desired points, that is such points in the Welt as are to be. attached to curved or other portions of'the work where it is desirable for proper attachment that the Welt should be slitted.
